I. Introduction
Frequency modulated continuous wave radar is a key technology in advanced driver assistance systems such as emergency break assist or adaptive cruise control. However, FMCW radar is prone to interference due to its emited wideband signal. More concretely, data delivered by an FMCW radar might be entirely corrupted if it is interfered by another FMCW radar (mounted on e.g., another car) operating in the same frequency range; This causes mutual interference as both radars are affected. A more detailed explanation of FMCW radar mutual interference can be found in [1], [2].
